ELIAS PX Manual 1.0
4 Connections and Control
Features
ELIAS EPX 112 A
1 Mode Switch
Operation: This switch configures the ELIAS PX
mid/high unit for use in full-range mode (without
subwoofers) or for use as a satellite in combination
with the subwoofer.
2 Ground
Ground Lift button for separating the signal and
chassis ground if humming noises occur. In the
event of low-frequency hum, engage the Ground Lift
switch. The ground circuit is severed when this
button is pressed. If this doesn’t solve the problem,
check for damage to any cord connected to ELIAS PX
as well as all cords routing signals to the mixing
console (see also Tips and Tricks).
3 Line In
Connecting cords: Connect cords carrying signals
from your mixer (master left/right, line out, or a
similar circuit) to the balanced inputs using a mic
cord equipped with XLR connectors.
Ensure XLR connectors are wired as follows:
1= ground, 2= +, 3= -.
4 Line Through
Connecting cords: Use this parallel output to route
the incoming line signal to other components (for
example, additional ELIAS PX systems or other com-
ponents) via XLR cords.
5 Gain
Operation: Use this knob to adjust the input signal
level. The standard setting is 0 dB at the 12 o’clock
position. For weaker signal sources such as small
mixers equipped with unbalanced circuitry and RCA
connectors or _" jacks, you can boost levels by up to
+6 dB (twist the Gain knobs to the far right).
6 Fan
This ventilator keeps the power amp modules cool.
Always make sure that the fan and the vents are free
of dirt and debris and that they remain unobstructed
so air can circulate freely.
7 Circuit Breaker
Operation: This automatic circuit breaker serves the
same purpose as a standard fuse. If it trips, first
switch the system off entirely (Power switch set to
OFF). Then after you have identified and fixed the
problem, you can reset the circuit breaker by simply
pressing it.
8 Mains Input
Connecting cords: Use the factory-included mains
cord to connect this socket to a wall receptacle.
Caution!
Make sure the local mains voltage matches
the voltage specified on the device. If you connect
the system to the wrong mains voltage, you may
destroy the ELIAS PX system’s electronic
components.
9 Power Switch
Operation: This is the on/off switch for the active
system. When engaged, the Power On LED lights up.
Always switch the ELIAS PX active system on last,
that is, after powering up all other components such
as the mixing console, and switch it off first before
powering down all other connected devices.
10 Power On LED
This LED lights up when the Power switch is set to
On and the system is connected to a mains power
supply.
11 Mains Cord Cleat
Secure the power cord with this cleat to prevent it
from being pulled out inadvertently.
5 Tips and Tricks
1 Do not expose electronic circuitry to moisture!
When you set the system up outdoors, be sure to
protect it against rain. Keep soft drinks, beer and all
other liquids well away from the cabinets to protect
their electronic components from short-circuiting.
2 Ensure that the vents on the enclosures’ rear
panels are free of dirt and the devices are ventilated
properly. Otherwise, the electronic components are
likely to overheat and be damaged by thermal
breakdown.
